Tesla Solar Roof Tiles

I love the company, and this idea, but can you see something wrong with the video of the solar roof tiles in the video https://www.tesla.com/en_AU/solarroof ? Some scientific thinking and you will leave you wondering about the authenticity of the demo. I assume the difference is legit but you should not be convinced by the video alone; or should you?

Bring on the science. What say you?
